What We Offer

Real Time GPS or GNSS Heading Determination:

Two GNSS antennas generate a vector in space that has both horizontal (azimuth) and vertical (pitch or roll) components

Heading and pitch/roll solutions between the antennas are computed using our ALIGN® heading engine

ALIGN’s heading accuracy is a function of the horizontal separation between the two antennas

Real Time SPAN® GPS/INS or GNSS/INS Heading Determination:

A SPAN system typically consists of one antenna, one GNSS receiver and also one Inertial Measurement Unit (IMU). Dual antenna SPAN GPS/INS systems are also available to enhance initialization time and long term stability of the system

In a SPAN system, heading (and roll and pitch) is computed using gyroscope data, accelerometer data (IMU) and GNSS data

Heading accuracy of a SPAN system is based on the accelerometer and gyroscope specification of the IMU being used and the type of motion encountered

Post-processed Heading Solutions:

Two GNSS receivers’ raw code and phase data can be post-processed in our GrafMov to obtain heading measurements

A GNSS receiver’s raw code and phase data plus IMU raw measurements can be post-processed in Inertial Explorer® to obtain roll, pitch and yaw measurements. The forward post-processed solution will be similar to the real-time SPAN system mentioned above
